Also, we analyzed that the mortgage to achieve renovation with energy efficiency and airtightness. As the result, we found the deterioration even in a housing after 90’s which used same construction method. We recommend renovating and at least to inspect a housing situation with air and thermal leakage. Also, in the areas where have high land price, the reverse mortgage is easy to apply.
